Question

2. What is the HCF of two consecutive
(a) numbers?
(b) even numbers
(c) odd numbers
3. HCFof co-prime numbers 4 and 15 was found as follows by factorisation:
4=2×2 and 15=3×5 since there is no common prime factor , so HCF of 4 and 15 is 0. Is the answer correct ?If not, what is correct HCF?
who answer first I will mark him as brainliest and ussles answers will be reported ​

Answer 1

(2).1. 1

2. 2

3. 1

(3). The answer is incorrect as the HCF of any no.s is 1 at least but 0 can never be the HCF of any 2 no.s even when the no.s are prime or coprimes.

The correct HCF of 4 and 15 is 1

Answer 2

Answer:

2.

a)

HCF of any two numbers will be 1 because they are not have any common factors.

b)

HCF of two Consecutive even numbers will be 2.

c)

HCF of two consecutive odd numbers will be 1.

3. HCF of any two numbers can't be zero because all numbers have 1 common factor that is 1. So, answer should be 1.
